CASH-REGISTER.

SPECIFICATION forming part of Letters Patent No. 470,247, dated March 8, 1892.

Application filed January 9, 1892. Serial No. 417,566. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES EDGAR LORD, a citizen of the United States, residing at Boston, in the county of Suifolk and Commonwealth of Massachusetts, have invented a new and useful Improvement in Cash-Registers, of which the following is a specification.

The object of my invention is to provide means for preventing a false registration being made.

My invention is especially adapted to that class of cash-registers in which the key actuates the registering mechanism upon its return movement, and consists in the mechanism hereinafter described for coupling all displaced keys during their preparatory motion and uncoupling said keys at completion of preparatory motion and before their return or registering motion.

My invention is illustrated in the accompanying drawings of a cash register, in which Figure 1 is a sectional elevation of a portion of a cash-register embodying my invention. Fig. 2 is a similar view showing the position of the parts when the key is depressed from its normal position. Fig. 3 is a sectional plan of a portion of a cash-register. Fig. t is a detail plan similar to Fig. 3, showing the coupler raised and disengaged from the keys. Fig. 5 is a side elevation of the key-coupler. Fig. 6 is a. section on line 6 6, Fig. 1. Fig. 7 is a detail section on line 7 7, Fig. 3.

Similar letters of reference indicate similar parts throughout the difierent views.

In the drawings, a a, represent portions of the frame of a cash-register, to which are pivoted upon the rod b the keys 0 c c. The keys 0 c c are each provided with a pawl cl, which engages with the registering-ratchet e in such a manner that it turns said ratchet and its accompanying registering mechanism upon the return movement of the key, all in a well-known manner.

The key-coupler F consists of a notched plate f, which extends across the machine above the keys 0 c c and is provided with arms f f, said arms being pivoted upon studs f to the frame a of the machine. The

keys 0 c c are each provided with projections c c, which are so arranged relatively to the key-coupler that when a key is depressed from its normal position, as in Fig. 2, the notched plate f of the key-coupler enters the space 0 on each of the keys that have been displaced, thus coupling all displaced keys together. It will be noted that on account of the relative positions of the centers upon which the keys and the key-coupler turn the key-coupler rides over the projection c on all keys which are in their normal position without entering the space 0 upon said keys.

When the key-coupler F is in its normal position, as in Figs. 1 and 3, the notches f are opposite the spaces between the keys 0 c 0, so that the teeth f of the plate f enter the spaces 0 011 all displaced keys. This relative position of the spaces in the coupler to the keys continues unchanged until the key has been depressed to nearly its full extent. When the key-coupler has nearly completed the upward movement imparted to it by the depression of the key or keys displaced, the arm f strikes the inclined projection a upon the frame a, and a continued upward motion of the coupler results in moving said coupler laterally upon its pivots from the position indicated in Fig. 3 to that shown in Fig. 4, thus bringing the notches f opposite to the keys 0 c 0, so that the displaced keys are uncoupled and free to return to their normal position. A spring f returns the key-coupler to its normal position, said key-coupler upon its return movement striking the incline a which moves the coupler laterally in the opposite direction to that in which it was moved by the incline a. To the end of the pivots f are screwed leather washers f to prevent the coupler from being moved laterally too easily by a jar.

It will thus be seen that when my improvement is applied to a keyed cash-register of the class in which the registration is effected upon the return movement of the keys it is necessary that all the keys which are displaced from their original position must move together in their preparatory motion and be uncoupled at completion of same before their return or registering motion.

What I claim, and desire to secure by Letpreparatory motion and before their registerters Patent, is ing motion, substantially as described, and

In acash-register, the combination, with the for the purposes specified. registering-keys, of the key-coupler adapted CHARLES E. LORD. 5 to couple the displaced keys together duringlVitnesses:

theirpreparatory motion and to uncouple said CHAS. S. GOODING, keys from each other at the completion of the THOMAS H. SEELY.
